16 gnutls_psk_client_credentials_t cred
17 is a gnutls_psk_server_credentials_t type.

19 gnutls_psk_client_credentials_function * func
20 is the callback function
21
23 This function can be used to set a callback to retrieve the username
24 and password for client PSK authentication. The callback's function
25 form is: int (*callback)(gnutls_session_t, char** username, gnutls_da‐
26 tum_t* key);
27
28 The username and key ->data must be allocated using gnutls_malloc().
29 The username should be an ASCII string or UTF-8 string. In case of a
30 UTF-8 string it is recommended to be following the PRECIS framework for
31 usernames (rfc8265).
32
33 The callback function will be called once per handshake.
34
35 The callback function should return 0 on success. -1 indicates an er‐
36 ror.
